Methods and systems for detecting a partial closure of a navigable element
First Claim
1. A method of identifying navigable stretches that are potentially partially closed in a navigable network within a geographic area, the method comprising:
- obtaining, by a server that comprises a processor and a memory, positional data relating to the movement of a plurality of devices along a navigable stretch with respect to time in a given time period;
determining that the given time period is a period of non-congested traffic flow for the navigable stretch;
using, by the server, the positional data to determine an average speed of travel along the navigable stretch in the given time period;
comparing, by the server, the average speed of travel to a free flow speed for the navigable stretch;
comparing, by the server, the average speed of travel to a threshold value; and
determining, by the server, that the navigable stretch is potentially partially closed when the given time is determined to be a period of non-congested traffic flow for the navigable stretch and when the average speed of travel is both lower than the free flow speed by a predetermined value and lower than the threshold value, wherein the threshold value is not set by reference to the free flow speed.

Abstract
A method of identifying navigable stretches that are partially closed, e.g. due to the presence of roadworks, in a navigable network within a geographic area. A server obtains positional data relating to the movement of a plurality of devices along a navigable stretch with respect to time in a given time period, wherein the time period is a period of non-congested traffic flow. The positional data is used to determine an average speed of travel along the navigable stretch in the given time period. The determined average speed of travel is compared to a free flow speed for the stretch, and the navigable stretch is identified as being partially closed when the determined average speed of travel is lower than the free flow speed by a predetermined value.

11. A non-transitory computer readable medium comprising computer readable instructions which, when executed by at least one processor of a system, cause the system to perform a method comprising:
-
obtaining positional data relating to the movement of a plurality of devices along a navigable stretch with respect to time in a given time period; determining that the given time period is a period of non-congested traffic flow for the navigable stretch; using the positional data to determine an average speed of travel along the navigable stretch in the given time period; comparing the average speed of travel to a free flow speed for the navigable stretch; comparing the average speed of travel to a threshold value; and determining that the navigable stretch is potentially partially closed when the given time is determined to be a period of non-congested traffic flow for the navigable stretch and when the average speed of travel is both lower than the free flow speed by a predetermined value and lower than the threshold value, wherein the threshold value is not set by reference to the free flow speed. - View Dependent Claims (12, 13, 14, 15)

16. A system for identifying navigable stretches that are potentially partially closed in a navigable network within a geographic area, the system comprising:
at least one processor, the at least one processor configured to; obtain positional data relating to the movement of a plurality of devices along a navigable stretch with respect to time in a given time period; determining that the given time period is a period of non-congested traffic flow for the navigable stretch; use the positional data to determine an average speed of travel along the navigable stretch in the given time period; compare the average speed of travel to a free flow speed for the navigable stretch; compare the average speed of travel to a threshold value; and determine that the navigable stretch is potentially partially closed when the given time is determined to be a period of non-congested traffic flow for the navigable stretch and when the average speed of travel is both lower than the free flow speed by a predetermined value and lower than the threshold value, wherein the threshold value is not set by reference to the free flow speed. - View Dependent Claims (17, 18, 19, 20)
